Broch (1934) beskriver beliggenheten som "Vel 100 m øst for sagen sydøst for Iversby kapell" ... "i utmark på Skjeberg kommunes grunn" ... "et mindre brudd 30-40 m fra landeveien. Bil kan kjøres frem til bruddet." Det er et åpent dagbrudd i vestskråningen av en knaus hvor gangen følger åssiden. Et annet brudd er beskrevet "Nogen hundrede meter sønnenfor er der i åssiden, like op for veien et noget mindre brudd." Begge ble drevet et par års tid rundt 1930 og det ble produsert kvarts og "3.sort" feltspat. |

Bør muligens flyttes, men det er usikkert hvor eksakt lokalitet bør være. Sagbruket som nevnes i stedsbeskrivelsen kan være Høyfoss sag i Buerbekken. |

Abstract: | |
In this publication, which is a sequel to Feltspat II and III by Olaf Andersen and Tom F.W. Barth, brief and exoteric descriptions and some information on production and history are given of about 180 individual feldspar, quartz, and mica deposits, all of them situated east of the river Glomma in south-eastern Norway. Particulars of purely geological or mineralogical interest are few; most of them are given as footnotes or in the preface, but the minerals of each deposit, exceot quartz, feldspar and mica, are listed. The deposits are cross cutting pegmatite dikes, with a northeastern strike and a steep dip. The dikes exhibit a marked zoning; moreover, they are remarkably free from rare minerals, the occurrences of which seems to be restricted almost entirely to the dikes near the Idefjord (Bohus) granite. |
